Maximize Caster Control and Front-End Stability

Upgrade your Jeep Wrangler JK (2007-2018) with the Cruise Series Front Control Arm Set, designed to restore proper caster angles, improve axle centering, and enhance overall drivability. Whether you're addressing factory alignment deficiencies or correcting geometry changes from a lift, this set provides the optimal balance of strength, adjustability, and control for both on-road stability and off-road articulation.

Key Features and Benefits

  • Regain Caster Improve Steering Control – Factory suspension geometry and small lifts reduce caster angle, leading to wandering steering and instability. This set corrects caster and re-centers the front axle, ensuring a more stable, controlled ride.
  • Heavy-Duty Steel Construction – Built to outlast and outperform factory control arms, these arms offer superior impact resistance and long-term durability.
  • Tapered Polyurethane Bushings for Responsiveness – Designed for improved articulation, vibration dampening, and better road feel, compared to standard rubber bushings.
  • Full Adjustability for Lifted Vehicles – Ideal for suspension lifts from 0 to 6 inches, restoring proper axle position and caster alignment to maintain smooth handling and reduced driveline vibrations. For lifts beyond 6 inches, contact us for additional solutions.
  • Complete Suspension Solution – For full control over axle positioning, pinion angles, and suspension geometry, pair this set with our Cruise Series Rear Control Arm Set (CRS-J-JK-RS4). Together, they provide a comprehensive upgrade for improved handling, stability, and long-term durability.

Two-Stage Powder Coating for Maximum Protection

Every Cruise Series Front Control Arm undergoes a two-stage powder coating process for maximum durability and corrosion resistance: Zinc primer base coat prevents rust and enhances longevity. Durable top coat available in 10 custom colors for added style and resilience.

Effortless Installation

The Cruise Series Front Control Arm Set is designed for quick and easy installation using factory hardware. For vehicles with rusted or seized bolts, we offer optional Grade 8 hardware kits separately to simplify the installation process.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Front Control Arm Set reflects the highest standards of American craftsmanship. By choosing CORE 4X4, you're investing in high-quality, American-made products built for the toughest driving conditions.

For a complete suspension solution, pair this with the Cruise Series Rear Control Arm Set (CRS-J-JK-RS4) to fully adjust and optimize axle positioning, pinion angles, and handling characteristics.

Upgrade today and experience better alignment, superior handling, and long-lasting durability with CORE 4X4’s American-made front control arms!

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.
